DISCUSSION AND 48-HOUR OUTLOOK
——————————
At 500 AM AST (0900 UTC), the center of Tropical Storm Danny was located near latitude 15.8 North, longitude 60.5 West. Danny is moving toward the west near 9 mph (15 km/h), and a westward to west-northwestward motion is expected over the next 48 hours. On the forecast track, the center of Danny will move across the southern Leeward Islands later this morning and afternoon, and move into the northeastern Caribbean Sea by this evening.
Reports from a NOAA Hurricane Hunter aircraft indicate that maximum sustained winds remain near 40 mph (65 km/h) with higher gusts.
Weakening is forecast during the next 48 hours, and Danny is expected to become a tropical depression by this evening, and degenerate into a remnant low tonight or on Tuesday.
Tropical-storm-force winds extend outward up to 60 miles (95 km) from the center.
The latest minimum central pressure reported by NOAA aircraft data is 1007 mb (29.74 inches).
